Description
Technical field
The present invention relates to a kind of crawler-tread tractor times formula driving device, be applicable to the crawler-tread tractor of rear-axle drive.
Background technology
Its engine power of existing crawler-tread tractor is passed to a power take-off shaft by mechanical drive change speed gear box power input shaft through tween drive shaft and is divided two-way to pass to two groups of high pulling torque steering clutchs and drg through one group of central authorities' drive bevel gear again, there are the following problems for this structure: 1. change speed gear box is shifting slide gear or engagement cover or synchro gearshift, can not realize power shifting, inefficiency, inconvenient operation; 2. steering clutch is arranged in after the central drive bevel gear, transmits moment of torsion and compares and improve greatly before being arranged in central drive bevel gear, often occurs skidding, the problem of heating, serious wear; 3. because the transmission moment of torsion improves greatly, steering force is very big, the chaufeur fatiguability; 4. drg is arranged in after the central transmission, and brake torque also improves before comparing and being arranged in central drive bevel gear greatly, thereby the inevitable increase greatly of brake dimensions, and drg heating, wearing and tearing also increase greatly.
The patent No. is 03245757.X, a kind of mechanism is disclosed in the Chinese patent of patent name for " continuously tracked vehicle braking and driver train ", mainly by rear axle housing body, central transmission device, the steering clutch assembly, brake assembly, final transmission housing, axle drive shaft, drive wheel, driving shaft gear, countershaft-gear, compositions such as upper cover plate.Brake assembly adopts the floating drg, and final driving device adopts two-stage spur gear drive structure.Power is imported by central transmission, and the deceleration of the central transmission of process and final transmission increases to be turned round, and is exported by drive wheel at last.The defective of this utility model patent is to be arranged on the driving dynamics that central transmission both sides steering clutch afterwards realizes cutting off and transmitting the both sides continuously tracked vehicle by separating and engaging with deficiency, realize stopping of two side drive wheel and slow down by being arranged on two side brakes after the central transmission, therefore must cause transmitting moment of torsion improves greatly, steering clutch, brake dimensions increase greatly, heating, wearing and tearing increase, thereby the life-span is very short.
The patent No. is 02228175.4, patent name discloses a kind of steering hardware for crawler-tread tractor, bulldozer and modified product thereof in the Chinese patent of " continuously tracked vehicle power differential speed turning mechanism ", mainly comprise central transmission, two planet rows, turn to miniature gears, turn to big gear wheel, turn to two-wheel, the HM Hydraulic Motor output gear, final drive shaft.Two planet toothrow circles are made of one and are connected with central transmission bevel gear wheel.Two turn to big gear wheel to be connected with two star row sun wheels respectively.Two groups of sun wheels, satellite gear, planet toothrow circle that the defective of this utility model patent and deficiency are, complex structure big with oad, making, tooling cost is high substitute two groups of steering clutchs, solve owing to be arranged on central transmission and transmit very big the skidding of steering clutch, heating, the wear problem of causing of moment of torsion afterwards; Turn to miniature gears with increase, turn to big gear wheel, turn to two-wheel, the HM Hydraulic Motor output gear particularly will increase by a cover HM Hydraulic Motor and hydraulic efficiency pressure system realizes the continuously tracked vehicle power differential speed turning.Above-mentioned two kinds of methods taking have brought very big difficulty for processing, making, the assembling of car load, and especially integral vehicle cost improves greatly, thereby practical application and popularization have very big difficulty.
The patent No. is 200520016487.9, patent name discloses a kind of mechanical speed difference reversing arrangement in the Chinese patent of " a kind of mechanical speed difference reversing arrangement ", mainly is made up of power input shaft, commutation transition axis, reversing shaft, power take-off shaft, final gear pair, commutation transition gear, commutation driving gear pair, output gear, reversing gear and brake equipment.Handle reversing gear and make the commutation driving gear pair by the engagement of commutation transition gear, can realize turning to.The defective of this utility model patent and deficiency are if be applied on the continuously tracked vehicle, this differential reversing arrangement must be installed in after the central transmission, the transmission moment of torsion of its left and right sides dental clutch and left and right sides drg is very big, and it is the description of 03245757.X to the patent No. that its defective and deficiency are similar to top; It two also will increase separately and overlap independently mechanical drive, and cost increases; Its three, when turning at a slow speed the power stream on limit to cut off and cause that the speed of a motor vehicle slows down when turning to, reduce work efficiency.
